To'oill whomz'tmoy concern:

Be 1t known. that l, VVENZL L'rZ, Aa cit1- zen of @Zeche-Slovakia, residing at 'Csepeh "near Budapest, Hungary, haveinvented cer- 5 tain new and useful Improvements in Furlthe bricks of. the oven jot the furnace, espe-- cially those located nea-r t-heentrance of the uel to the furnace, Where the gas `and air are mined` and combined by combustion. ln qeneralth'e means which l provide Yfor ac- `onaplishing this purpose consiats ot a special torni oi" head for introdiieing the air and gas into the furnace, and. also for conveying the burned gases out of the furnace; similar heads beinea positioned at each end et the furnace, and each being' supplied with ni'eans for alternately passing fuel to the furnace or passing` the burned gases away from tho furnace. By this arrangeW nient, u ile one headis supplying fuel at one endof the furnace, the other head is passing the burned gases to the reeuperator or chimney frein `the other end ol the furnace.KV vlfhen ,the bricks at the combustion end ofthe furnace are becoming overheated the heads areg'eversed so that the cooler' burned gases pass-out at the heated end` and the cooler end becomes temporarily the combustion chamber; By thus reversingv the position and function of" the heads often as be necessary, perhaps every thirty minutes, the .tei11pe;,atur'e of' the bricks surroundiiug the combustion end of the furnace is maintained lower and injury thereto is materially reduced,

Off vthe drawings Fig. l shows a .Martin furnace according `to the invention, in cross .seetion; and Fig. 2 is` a plan vievv of the same with one end thereotin section.

vWards the vfurnace c and arranged to produce a vsuitable daino; d is a flue for conveying the burned gases to the chimney, and it is built in the saine head g as the fuel flue.

lllhen reversing the direction or". the flow of thc furnace.

rangements, the lire-bricks in the neighborhood o'f the combustion chamber are alternately heated by the hot ,eases as the air and tuel gas are combinethand cooled by'thel cooler burned as they pass out at that end of the furnace; and it will be the saine with the lire-lu'icks adjacent the other end ot rl`he idle fines are kept from coolingv oil' bysuitable walls, gates, and so forth; and means may be introduced to heat the idle dues, such as a ras flame.

rPhe tivo heads may be moved across the ends olt the 'furnace simultaneously, so as to alternatelysupply"fuel to the furnace and receive burned gases from the furnace, by the use ot any suitable mechanism', electrically or mechanically, or by the use o't the cylinders 7L suitably supplied with coinpressed air.

nv suitable means Inav be Jrovided Jfor .f Y .l

prcuierlyy controlling the gas passageways when the heads are movefh l' prefer for the purpose to providcllues 'i and which are adapted to register with fthe pi ageways a and 71 respectively, when the air and is being supplied, andwllich register .with the passagexvzr .cl when `the burned rases are to be removed. The lues tron'r each end ot the 'furnace are operatively connected with a fouravay valve casing Z'eavhieh is operatively connected With the chimney/Z andWit-h a pipe m, the pipe m being'A operative-ly connected with any suitableV source of 'gas supply; The easing is provided with a 'rotatable valve n which is adapted to close the gas supply to one head and to open it to the other when the heads are shifted, and at the saine time to correspondingly open and close the chimney flue. Similarly the ilues y' are connected with la four-Way valve easing 0 which is also operatively connected to 'the `air 'to pass to ythel left-hand head when it is desired and at vthe same time 'to allow the burned gase'to pass; from the other head and to 'reversethis process. riny suitable vmeans may be used orrotating the valves when .the heads are shifted.

ln order to more satisfactorily carry out my invention I provide, between the furnace and each head, plates fr and e. The plate r is fixed to tshead,and has openings t there4 rie ypiates the leakage ot gas and injury to the adjacent portions of the head and furnace may he materially reduced. Flanges f1) on theplates sliniit the movement ot the heads.

The plate .si also closes the openings which are not in operative position, and'thus reduces thercooling tendency ot the interior surfaces otjthe passageways which are not operating. i

erin order to still further reduce the cooling ot the unused passageways l provide openings le in the plate swhich are arranged to be operatively connected to suitable sources o' supply ot air and combustible gas. which,` when the 1' assageways are in idle position, produce a flame therein which maintains the required temperature ot' the walls ot the passageways. The arrangement ot the plates and openings such that the passageways vl* arel closed b v the plates vr when the passageways are not registering with the idle openings zin the plates r.

Any suitable means may be used for keeps ing the edges ot theopenings and n. 'troni becoming overheated, such asl by passing water or steam through the chambers m surrounding the openings. The valves n and Q are operated automatically as the head vf/ is shifted by means of an arm links o. and the gear-wheels 0'; the arrn being fixed to one wheel, and the wheels meshing and being fixed respectively to the valves. it is to be understood that the drawings are more or.

less diagrannnatio.
